THREAD-COUNTING- APPARATUS.

i Application led December 26, 1923. Serial No. 682,847.

To all whomfz't may concern:

Be it known thati GEORGE l-I. RosENsTEIN, citizen of the United States, residing at New York city, in the county of New York and State of New York, has invented certain new and useful Improvementsk in Thread- Counting Apparatus, of whichthe following is a specification.

This invention relates to thread counting apparatus.

`Among the objects of the invention is to provide an apparatus of the character described which shall be simple in construction and manipulation, compact and neat in arrangement, coniparatively cheap to manufacture, and efficient in operation to a ligh degree. Other objects of this invention will in part be obvious and in part hereinafter pointed out.

`The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter describedapd of which the scope of application will be indicated in the follo`wing claims.

In the accompanying drawing, in which line 4-4 of Fig. 3 showing the screw bolt and indicator.

Referring in detail to the drawing, indicates a case or container having hinged thereto a cover 11. The case is divided into a plurality of compartments by means of a suitable partition 12. In one ofthe compa-rtments is held an electric battery 13, the

poles of which are vadapted to makecontact `with contact studs 15, a, the former being connectedby means of lead lwires 16 to one rend of a switch 17 positioned on one outer face of the case 10, theother stud 15a being connected yto one pole lofan electric bulb 18 as by means vof the lead wire 19.l A lead Vmore fully described.`

wire 20 connects the opposite pole 21 of the electric bulb to the other pole 22 of the switch 17, so that when the switch 17 is closed a complete circuit is made through the battery and electric bulb' aswill be read-n ily understood.

The counting device is indicated generally at 23 and comprises a right angle bracket member having a horizontal portion 24 and which is aperturedl as at 25 for a lens 26. The latter may be held securely in position in the member 24 in any suitable manner. In the form shown in the drawing, a wire ring 27 snapped into a groove formed in the wall of the aperture serves this purpose. The vert-ical face 28 of the bracket is recessed so as to provide a window .29c for admission yof light, and has preferably formed integral therewith a base member 29 extending from the bottom thereof substantially at right angles thereto and parailel to the first mentioned horizontal member 21. The bottom of this face is preferably reained out as at 2921 so as to provide a progressive taper towards the forward portion of the base, and at the forward portion the upperpart of Ithe base is tapered downward so as to providea flat edge o-r scale 30 on which may be marked` any desired scale division 31. The reamed out portion 29a permits use of the device with heavier cloths and the taper resulting in the portion 30, provides a sharp edge for holding down the cloth under examination. Hinged adjacent the bottom of the vertical member 28, as at 32, is a flatextension 33 whereby the counting device may be supported or held on the top of the cover 11 in any suitable manner. In the form shown in the drawing, the counting device is removably held on the cover by means of a pocket 84 formed from sheet metal S5 or the like material having depressed end portions 35, whereby the pocket .is secured to the cover as by screws 3G. The extension 33 is slipped into this pocket and the bracket may then be tilted about the hing 32 so as to lift thebase 29 when itis desired to position the fabric to be tested as hereinafter Upstanding from the upper face 29b of the base 29 area pair of trunnions 37, 3T in whichis journaled a screw bolt 3S having a head 39, at one end, and held against longitudinal movement by a .small screw and a washer 4.1 at the other end. Carried on soy the screw bolt is ai nut 42 from which en tends an indicator 43 bent downward so as to extend over the scale 30.

In the portion of the cover disposed over theY bulb inthe interior of the case is formed a. window for a pane 44 preferably of smoked glass heldlin position by means of a suitable frame 45. i

The cloth to be tested is placed over this smoked glass and then the threads counted by manipulating the' screw bolt 38 so as to cause the indicator 48 to move over a desired distance on the scale, each thread being counted, of course, as the vpointer passes it.

It will'be noted that the upper horizontal member'24 extends'considerably beyond the baseQQ, thusproviding--an overweight which causes thebracket ful'crumed at 32 to bear downward onf-the edge against the cloth thus holding-it securely imposition while the clotlris 'beingl tested. The bulb 18 proides sufficient light through lthe smoked glassfor/lighting-upA the field of vision and the lens QGf'of the window 29 further provide sufficient' light' from the outside so' that theV dialv may` be read andthe apparatus easily operated.

The apparatus as-herein described coniprises Va compact, portable uniti that may be easily carried froml place to place and so arranged that the"countingdevice proper is safelylieldxwithin'the case when not in use, and may be removably attached tothe top of the case in position for use.

It`will thus be seen that there is provided a Vdevice in` which the severall-objects'of this invention areaohievedand which isz well adaptedto meet the conditions of practical use.H A
